This is on purpose: abort() is being called since it can't connect to the database server. The techempower executable is supposed to be used for the TechEmpower Web Framework benchmarks, and requires a setup of their environment.

xyproto commented 8 years ago

I see. It's a bit unusual to abort() instead of writing to stderr and exiting with an error code >0.

fix it pls........
